Types

type Machine 

type Machine = zip.Object[MachineSpec, MachineStatus]

Machine is the mutable API object that represents a machine instance.

type MachineList 

type MachineList = zip.ObjectList[MachineSpec, MachineStatus]

MachineList is the mutable API object that represents a list of machine instances.

type MachinePort 

type MachinePort struct {
	// If specified, this must be an IANA_SVC_NAME and unique within the host.
	// Each named port on the host must have a unique name. Name for the port that
	// can be referred to by services.
	Name string `json:"name,omitempty"`

	// Number of port to expose on the host.  If specified, this must be a valid
	// port number, 0 < x < 65536.
	HostPort int32 `json:"hostPort,omitempty"`

	// Number of port to expose on the machine's IP address. This must be a valid
	// port number, 0 < x < 65536.
	MachinePort int32 `json:"machinePort"`

	// Protocol for port. Must be UDP or TCP. Defaults to "TCP".
	Protocol corev1.Protocol `json:"protocol,omitempty"`

	// What host IP to bind the external port to.
	HostIP string `json:"hostIP,omitempty"`

	// MAC address of the port.
	MacAddress string `json:"macAddress,omitempty"`
}

MachinePort represents a network port in a single container.

func ParsePort 

func ParsePort(s string) ([]MachinePort, error)

ParsePort parses a string representation of a MachinePort and returns the instantiated structure. The input structure uses nerdctl's implementation which in itself follows the traditional "docker-like" syntax often used in a CLI-context with the `-p` flag.

type MachinePorts 

type MachinePorts []MachinePort

MachinePorts is a slice of MachinePort

func (MachinePorts) String 

func (ports MachinePorts) String() string

String implements fmt.Stringer and outputs MachinePorts in human-readable format.

type MachineService 

type MachineService interface {
	Create(context.Context, *Machine) (*Machine, error)
	Start(context.Context, *Machine) (*Machine, error)
	Pause(context.Context, *Machine) (*Machine, error)
	Stop(context.Context, *Machine) (*Machine, error)
	Update(context.Context, *Machine) (*Machine, error)
	Delete(context.Context, *Machine) (*Machine, error)
	Get(context.Context, *Machine) (*Machine, error)
	List(context.Context, *MachineList) (*MachineList, error)
	Watch(context.Context, *Machine) (chan *Machine, chan error, error)
	Logs(context.Context, *Machine) (chan string, chan error, error)
}

MachineService is the interface of available methods which can be performed by an implementing machine platform driver.

func NewMachineServiceHandler 

func NewMachineServiceHandler(ctx context.Context, impl MachineService, opts ...zip.ClientOption) (MachineService, error)

NewMachineServiceHandler returns a service based on an inline API client which essentially wraps the specific call, enabling pre- and post- call hooks. This is useful for wrapping the command with decorators, for example, a cache, error handlers, etc. Simultaneously, it enables access to the service via inline code without having to make invocations to an external handler.

type MachineServiceHandler 

type MachineServiceHandler struct {
	// contains filtered or unexported fields
}

MachineServiceHandler provides a Zip API Object Framework service for the machine.
